About Primates

There are 376 species of primates in the world—from humans and apes to monkeys and prosimians ("premonkeys").

The smallest primate is the pygmy mouse lemur, which can fit in the palm of your hand. The largest—the gorilla—can weigh more than 400 pounds. Most primates live in warm climates, and most depend on forests for their survival. More Primate Facts
